# Roots
Roots contain cached statistics and recovery information.
Because there is only a single root at any time, the root is not named. Instead, it is accessed via `FMTCRoot` - and all members are static.
// final root = FMTCRoot;
final size = await FMTCRoot.stats.realSize;
After the root reference is constructed, the following actions can be performed with it:
{% hint style="info" %}
Management of the root is not provided by `FMTCRoot`. Instead, the backend should implement any necessary methods.
{% endhint %}
